IMPROVEMENT IN CHIMNEY-CAPS.

Specification forming part of Letters Patent No. 183,581 dated October 24, 1876; application filed 7 October 6, 1876;

To all whom it may concern.-

Be it known that I, FREEDRIGK LIGHTEN- FELs, of Newark, in the county of Essex and State of New Jersey, have invented a certain Improvement in Chimney Tops or Gaps, of which the following is a specification:

My invention consists in the employment of certain mechanism in making an adjustable chimney top or cap. 4

Figure 1 is a plan view. Fig. 2 is a crosssection on the line as w.

My cap is usually made of sheet metal, but may be made of cast-iron, if preferred, and is in two sections, A and B. The latter is made with ribs 0, fitted to slide in the grooves D on the under side of the section A, adjusting the cap to chimneys of different width. These ribs and grooves also assist to stiffen'the sec- These sections are locked together by a bolt, E, put through the holes 6 of the two, and held in place by a key, 2'. Some other equivalent or well-known devices may be em-, ployed for holding the two together.

On the under side of the sections are secured, to each section, two sockets, n, just so far from the outside that the bracket-supports 'v, fitted into them, will have their lower ends tolextend down into the top of the chimney S sufficiently close to hold the cap in position by the friction of the pressure against the insides of the ribs 0 and grooves D, and locked by means of the bolt E and key 6, and having'the bracket-supports'v fitted to the sockets n, substantially as and for the purpose specified.
